Once you've defeated Olcadan, it's OK to lose (i.e. it doesn't matter if you lose to Zasalamel in Lost Cathedral)and the first 'Prepare to defend yourself' challenge is an extra fight, so that one doesn't matter either.
Also, I've discovered Siegfried's route
Episode 1: Old Toledo: vs Swordsman
choose to search for power to destroy Soul Edge.
Episode 2: Lakeside Coliseum: vs Rock
Episode 3: Clock Tower: vs Zasalamel

Episode 4: Proving Grounds: vs Kilik
if you choose to stop

Episode 5: Kuneptu Shrine Ruin: vs Astaroth
Episode 6: Ryuku Port: vs Maxi (don't ring out)
choose to search for the man
Episode 7: Labrynth (corridor): destined battle: vs Raphael
